The best automatic litter box for most homes is the Litter-Robot 4 — a self-cleaning box that sifts waste into a sealed drawer after every visit and tracks each cat’s weight and bathroom habits in an app. That last part matters more than it sounds: changes in litter-box frequency are often the first sign of a urinary or kidney problem, so a box that quietly logs the data can flag trouble early. Below are the self-cleaning boxes we’d actually trust with our own cats — every one confirmed in stock, across every budget.

Automatic cat litter boxes: the 6 best, compared
The 6 best automatic cat litter boxes, ranked
1Litter-Robot 4 by Whisker Best overall
The gold standard. After your cat steps out, a patented sifting cycle separates clumps from clean litter into a sealed, carbon-filtered drawer — so there’s a fresh bed every time and you empty it roughly once a week. The Whisker app logs each cat’s weight and bathroom frequency and flags abnormal changes, which is genuinely useful for catching urinary or kidney issues early. Works with any clumping litter and safely handles up to four cats. Pricey, but it’s the one most people wish they’d bought first.
- SELF-CLEANING LITTER BOX: Never scoop again with Litter-Robot 4 - the automatic, self-cleaning cat litter box. The patented sifting process automatically separates your cat's waste from the clean litter. Just empty the waste drawer when full.
- MONITOR + CONTROL VIA APP: Control the smart litter box straight from the Whisker app. Monitor waste and litter levels in real time, get health insights, and track kitty's weight after each use.
2Casa Leo Leo’s Loo Too Best premium alternative
A near-silent (under 30 dB) globe-style self-cleaner with Wi-Fi app control, Alexa and Google voice, UV odor control, and anti-pinch safety sensors.
